Due to the fact that they require Hall technology to function, 3D omniposition sensors are often referred to as 3D Hall effect sensors. A magnet is placed perpendicular to a flat conductor that is working with either (the north or south) magnetic pole to produce detectable voltage using the Hall effect, a time-tested technique for measuring magnetic fields. They function with either a strong positive or strong negative magnetic field and are a form of digital output Hall-effect latching switch.
The Global 3D omnipolar sensor market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Allegro MicroSystems Europe’s A1266 is a special 3-dimensional sensor IC that combines vertical and conventional planar Hall-effect sensor ICs to be able to detect magnetic fields of either polarity in any direction.
The new device’s omnipolar, omnidirectional sensitivity makes it perfect for spotting magnetic manipulation in electronic locks, smart metres, ATMs, gaming machines, and ticket machines. The A1266 can also be used in applications like games, consumer electronics, and white goods as a general-purpose magnetic switch that is nearly indifferent to magnet orientation or polarity.
It is not practical to use a single circuit board and only surface-mount components, but this little surface-mount SOT23 IC is functionally comparable to an array of three ordinary Hall-effect sensors arranged in three distinct orientations. The A1266 has better sensitivity than most traditional Hall-effect switches with a typical BOP working point of 25 G, enabling high-sensitivity 3D tamper or proximity sensing in a smaller package with less expensive assembly.
